Paolo Porpora occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #F5F6F4 claims 34.1% of the surface, functioning as the work's tonal foundation. The saturated accent, #DFC99A, registers at 5.5% - sparse enough to feel like a deliberate surprise. A value spread of 72 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 2 sits within the larger chromatic argument that Paolo Porpora's complete body of work advances.
